Panel Scrollbars [Resolved]

[RobDog888]

How can I detect if the scrollbars are visible or not on a panel
that has the AutoScroll property set to True?

This doesn't work.

If pnlPanel.ScrollStateVScrollVisible = True Then

Thanks in advance

ScrollStateVScrollVisible is a constant, not a property or anything. That's why that doesn't work.

If you inherit from Panel, you can check the VScroll and HScroll properties. They are Protected, so you can only access them through inheritance. Otherwise this should work...

Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As IntPtr, _
                                                                                ByVal nIndex As Integer) _
                                                                                As Integer
 
    Private Const GWL_STYLE As Integer = (-16)
    Private Const WS_VSCROLL As Integer = &H200000
 
    Private Sub Panel1_StyleChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Panel1.StyleChanged
        Me.Text = ((GetWindowLong(Panel1.Handle, GWL_STYLE) And WS_VSCROLL) = WS_VSCROLL)
    End Sub

This appears to work as well:

If Panel1.DisplayRectangle.Height = Panel1.Size.Height Then
            MsgBox("No Scroll")
        Else
            MsgBox("Scroll")
        End If

Thanks guys. I will try out both versions tonight when I get home.

Ok, I got both of them to work. I guess its just personal preference
of which programming logic to use.

Thanks guys for the help.
